一种具有pH响应性油水分离材料及其制备方法与应用
摘要：
本发明公开了一种具有pH响应性油水分离材料及其制备方法与应用。该制备方法先将基材预处理，配置胺类单体溶液，将基材浸泡在胺类单体溶液；然后配置胱胺溶液，将处理后的基材浸泡在胱胺溶液中，清洗干燥后浸泡于还原溶液中；将含不饱和键的功能单体与含不饱和键的pH响应单体溶于有机溶剂中，再加入光引发剂得到混合单体溶液，处理所得基材浸泡于混合单体溶液中，置于紫外光下光照，清洗，干燥。该材料在酸性与中性时表现为超疏水/超亲油性能；在pH＝12时，此材料将会由超疏水/超亲油性能转变为超亲水/水下超疏油性能。本发明实现可控的重油、水与轻油之间的油水分离，在污水处理、油水分离以及处理深海石油泄漏中具有应用前景。
摘要（英）：

The invention discloses a pH-responsive oil-water separation material and a preparation method and application thereof. The preparation method is as follows: first pretreating a substrate, preparing an amine monomer solution, and soaking the substrate in the amine monomer solution; preparing a cystamine solution, soaking the treated substrate in the cystamine solution, washing, drying, and soakingthe substrate in a reducing solution; dissolving a functional monomer containing an unsaturated bond and a pH-responsive monomer containing an unsaturated bond in an organic solvent, adding a photoinitiator to obtain a mixed monomer solution, immersing the obtained substrate in the mixed monomer solution, illuminating under ultraviolet light, washing and drying. The material exhibits superhydrophobic/superlipophilic properties when being acidic and neutral; when pH=12, the material changes from superhydrophobic/superlipophilic to superhydrophilic/underwater superoleophobic. The pH-responsiveoil-water separation material realizes controllable separation of heavy oil, water and light oil, and has application prospects in sewage treatment, oil-water separation and treatment of deep sea oilleakage.
